[jCharts-users] X11/UNIX problem again

[Ashley T. <at...@uk...>]

Im having problems with this X11 (Unix based problem). Basically i got =
the code working on windows but not solaris, i've tried the=20

 try{  System.setProperty("java.awt.headless","true");}catch( Throwable =

fix but it doesn't seem to be working, im not sure if i've got it in the =

[jCharts-users] how to: different colored bars in one set of values?

[mr. t <gui...@ya...>]

I'd like to display a bar chart of a single set of values where each
bar's color is determined by its value.  e.g. if a bar's value is
over 3 make it blue, if it's under 2 make it red, green if it's
between 2 and 3.  I'm not seeing how that'd be done.  Is there a good
way?  I suppose I could split the one set into 3, then do a stacked
bar chart where all points in the first set are red and set to 0
unless it's over 3, and so on for the other two sets.  Seems a bit
circuitous.  tia.

Hello,

I have the same problem. Can't seem to find a way to show Value Labels in

Currently, I am using version 7.0.0

Hi Friends,

    But in documentation, it is given as "It is now possible to display
value labels on your Bar and Clustered Bar charts, but not Stacked Bar

there any way to use value labels in Line Charts ?

Thanks in Advance

Re: [jCharts-users] Requirement related to BAR Chart

[Nathaniel G. A. <nat...@ya...>]

You can create an Implementation of the PreAxisValueRenderListener to change the Paint
implementation used for each bar.


For an example see the src for the following implementation:
BackgroundRenderer backgroundRenderer = new BackgroundRenderer( new Color( 20, 20, 20, 50 ) );
barChartProperties.addPreRenderEventListener( backgroundRenderer );

Hi,
  I need to paint each of the BARS for the Chart Type 'BAR' using =
different paints.
The current library supports this type of feature only for 'Clustered =
Bar' and 'Stacked Bar'.

Can you give me pointers on what I need to change in the existing code =
to achieve it.

Re: [jCharts-users] Support for XYZ axises?

[Michael E. M. <mm...@nc...>]

I am writing a small GUI for a friend who wants data to be graphed using
three axises. He has data for the X, Y and Z axis. 

So far the only API I have found that supports this is a commercial
package which is not an option... 

Hope that explains it?.?. 

Later
Michael

Hello,

I am in need of an API that supports the XY and Z axis.

I can't tell if you are not importing it as I do not have your source. Do you have an import
statement for it?

I found how to make the vertical ones in the manual, but no luck with

For some reason I need to reboot my servlet container (tomcat) when I

This is working for me now.

Thank you for all your help!

I was able to find out my problem, however this is my new problem.
My Y-Axis is incrementing by 100. My highest data element only goes to
24.
So I tried:

		try
		{
			dataAxisProperties.setUserDefinedScale( 0, 50 );
		}
		catch( PropertyException propertyException )
		{
			propertyException.printStackTrace();
		}

But It still goes 0, 100, 200, 300, 400.
When I remove the code, it still does the same thing.

Any Ideas?

Thank you, once again.

I don't think your code is correct.  Are you sure you want
'amount_of_rows' for each dimension of
the data array?

Where is the ChartStroke class?

Whenever I call it like this it cannot be found:

ChartStroke xAxisGridLines=3D new ChartStroke( new BasicStroke( 1.0f ),
Color.red );

Is it outdated? Am I not importing it?

Thank you!
